Embodiment An embodiment of the present invention will be described below with reference to the drawings. That is, FIGS. 1 to 4 are views showing a pedal type trash can according to the present invention. The trash can includes a trash can body 1 having an upper opening and a trash can body 1 formed of synthetic resin. 2, a lid 3 rotatably supported on the trash can body 1, a pedal member 4 provided on the bottom rear surface side of the trash can body 1, a pedal 4 and a lid body on the back side of the trash can body 1. A link 5 for connecting 3 to each other, and a middle frame 19 which is fitted in the opening 2 when used and which opens and supports the opening of a dust bag (not shown).

The trash can body 1 has a bottom 6 formed in a raised bottom shape, and a bottom groove 7 extending in the front-rear direction is formed on the back side of the bottom 6. One end of the bottom groove 7 opens to the front surface 8 of the trash can body 1 formed in an arcuate horizontal cross section, while the other end of the bottom groove 7 opens to the back surface 9 of the trash can body 1 and the bottom surface 9 has a bottom. A back groove 10 is formed continuously with the groove 7 and extends in the vertical direction. The pedal member 4 is housed inside the bottom groove 7, and the pedal member 4 is axially supported by the trash can body 1 at its longitudinal center portion so as to be operable like a seesaw. A pedal portion 41 is formed at one end of the pedal member 4 exposed on the front surface 8. The link 5 is housed inside the back groove 10, and one end on the lower side thereof and the other end of the pedal member 4 are connected to each other.

Further, a reinforcing flange 12 is formed on the opening edge 11 of the trash can body 1 over the entire circumference, and from the flange 12 to the back face 9 on the opening 2 side of the trash can body 1. The main body side hinge portion 13 is formed. The main body side hinge portion 13 has a pair of side wall portions 14 and 14 which face the back surface 9 and the flange 12 and face each other across the back groove 7 and project rearward. Between the pair of side wall portions 14 and 14, a U-shaped body-side regulating portion of the present invention, which extends in the transverse direction of the back groove 10 and forms a rectangular hole 15 together with the back groove 10. The portion 16 is formed. Shafts 17 are formed on both outer side surfaces 14a, 14a of the pair of side wall portions 14, 14 so as to project along the axis of rotation of the lid 3. The corner 16a on the rear side of the U-shaped portion 16 is formed to be slightly curved, and both shafts 17 and 17 are obliquely cut out at the upper side of the tip portion.

On the other hand, the lid 3 described above has a shape to be fitted onto the opening 2 of the trash can body 1, and a flange 31 is formed on the peripheral edge of the trash can body 1 toward the back side. The flange 31 is notched in the middle part of the back side that is fitted onto the back surface 9 of the trash can body 1, and in the notched part, the lid side hinge part 32 protruding toward the rear of the lid 3 is provided. Are integrally formed. The lid side hinge portion 32 has a step with the surface of the lid body 3, extends along the rotation axis of the lid body 3, and covers the entire extending direction of the U-shaped portion 16 described above. It has a plate-shaped eaves portion 33 which is a lid-side regulating portion of the present invention, which covers the lid 3 and regulates the fully opened position of the lid 3 by being pressed by the back surface 16b of the U-shaped portion 16.

Further, the lid side hinge portion 32 extends from the notched end portion of the flange 31 and is continuous with both end sides in the extending direction of the eaves portion 33, and a pair of the main body side hinge portion 13 is provided. It has a pair of holding pieces 34, 34 for holding the side wall portions 14, 14. Bearing portions 35, 35 are provided on both inner side surfaces of the pair of holding pieces 34, 34 so that the bearing portions 35, 35 are fitted onto the shafts 17, 17 of the main body side hinge portion 13. Thus, the lid body 3 is rotatably supported by the main body side hinge portion 13.

Further, in the bearing portions 35, 35, when the lid 3 is opened, the back surface of the eaves portion 33 comes into sliding contact with both end portions of the U-shaped portion 16 while being pressed by the elastic force thereof. Moreover, the positions of the two holding pieces 34 are preset so that the lid 3 is biased in the closing direction when the lid 3 is at the fully open position. On the back surface of the lid body 3, a pair of link receivers 36, 36, which are located slightly forward of the axis of rotation of the lid body 3 and face each other, project from each other. The link receivers 36, 36 are loosely inserted in the holes 15 formed by the mounting portion 13, and the upper ends of the links 5 are connected to each other.

In the present embodiment configured as described above, when the pedal portion 41 is stepped on and the link 5 connected to the lid 3 is opened, the lid 3 is moved from the fully closed position shown in FIG. The opening operation is performed to the fully open position shown in FIG. 6, and the opening 2 of the trash can body 1 is opened. On the other hand, immediately after the opening operation, the lid body 3 swings in the opening / closing direction due to inertia, but the lid body 3 is restrained from rotating in the closing direction by the link 5 at the time of the opening operation. At the same time, since the eaves portion 33 of the lid body 3 is pressed against the rear surface 16b of the U-shaped portion 16 of the trash can body 1 to restrict the fully open position, not only the pivoting in the opening direction but also the closing direction is performed. Rotation is also suppressed.

Therefore, during use, it is possible to immediately stop the fluttering of the lid 3 immediately after being opened, and as a result, it is possible to improve the quality of the trash can. Moreover, since the structure is simple, the manufacturing cost of the trash can does not increase, and the trash can with improved quality can be provided at low cost.

Further, in the present embodiment, since the eaves portion 33 biases the lid body 3 in the closing direction with the opening operation of the lid body 3, the above-mentioned closing direction of the lid body 3 is determined. Rotation is suppressed more effectively. Therefore, the effect of suppressing the flapping is great.

Further, in this embodiment, as the lid 3 is opened, the eaves 33 is brought into sliding contact with the peripheral surfaces of both ends of the U-shaped portion 16 along the axis of rotation of the lid 3. For this reason, the rotation resistance of the lid body 3 with respect to the U-shaped portion 16 is large, and the lid body 3 immediately after the opening operation is not only prevented from rotating in the opening / closing direction as described above, but also has a U-shaped portion. Rotation in the opening / closing direction is braked by the sliding resistance between 16 and the eaves 33. Therefore, the effect of suppressing the fluttering is greater, and the fluttering of the lid 3 during use can be immediately stopped.

In this embodiment, the lid 3 is rotatably supported on the trash can body 1 by the shafts 17, 17 provided at both ends of the U-shaped portion 16 along the axis of rotation. However, the eaves portion 33 covers the entire area of the U-shaped portion 16 in the extending direction, and the back surface side of the eaves portion 33 is pressed against both ends of the U-shaped portion 16 as the lid 3 is opened. It has a structure that Therefore, even if the lid side hinge portion 32 is bent by the reaction force applied to the eaves portion 33 pressed by the U-shaped portion 16, the eaves portion 33 is displaced in the direction away from the U-shaped portion 16. The amount can be reduced, and the eaves 33 can be pressed against the U-shaped portion 16 more strongly. This also increases the effect of suppressing the flapping.

Further, in this embodiment, since the lid body 3 is made of synthetic resin and the eaves portion 33 is integrally formed with the lid body 3, elastic force of the eaves portion 33 is used without using other parts. The lid 3 in the open state can be biased in the closing direction. Therefore, the trash can can be manufactured at a lower cost without increasing the number of parts and the number of assembly steps. Regarding the above-mentioned effects of the present embodiment other than this, even if the main body side hinge portion 13 and the lid side hinge portion 33 are provided by attaching separate members to the trash can body 1 and the lid body 3, , Can be obtained as well.

7 and 8 are views showing another embodiment of the present invention. The trash can of this embodiment will be described below. On the back surface 33a of the eaves 33 of the lid-side hinge 32, the portions close to the pair of bearings 35, 35, that is, the lid 3 is in an open state. At this time, the convex portions 51, 51 are formed so as to project at the portions pressed by both end portions of the U-shaped portion 16 of the main body side hinge portion 13.

The U-shaped portion 16 has a sectional shape as described below. That is, the first point at which the convex portion 51 starts the sliding contact in the range in which the convex portion 51 slides when the lid 3 rotates on the surface of the U-shaped portion 16, that is, on the sliding contact surface of the present invention. P, and the second point at which the convex portion 51 contacts when the lid 3 is in the half-open position (the position that is rotated about 45 ° from the fully closed position) is Q (corner 16a of the U-shaped portion 16 in this embodiment). When the lid 3 is at the fully open position, R is the third point where the convex portion 51 contacts, and O is the rotation center of the lid 3 (center of the shaft 17). Distances OP to each point QPR, O-Q, and O-R are (O-P) <(O-R) <(O-Q), and have a gently changing cross-sectional shape. . In other words, before the cover 3 reaches the fully open position, the frictional force generated between the U-shaped portion 16 and the convex portion 51 increases once and then decreases instantaneously. Since the cross-sectional shape and other configurations are the same as those shown in FIGS. 1 to 6, the same reference numerals are given and the description thereof will be omitted.

In the present embodiment having such a configuration, the rotational resistance of the lid body 3 at the time of the opening operation increases once before the lid body 3 passes the half-open position and reaches the fully open position, and then decreases instantaneously. For this reason, the speed of the lid body 3 that is opened is reduced once before reaching the fully open position, and the impact when the lid body 3 reaches the fully open position is alleviated. Therefore, the swinging of the lid body 3 due to the reaction of the impact is suppressed. Therefore, also with this, the flap of the lid 3 can be immediately stopped. At the same time, the impact load on the eaves 33 during the opening operation of the lid 3 can be reduced, so that the durability of the trash can can be improved. The cross-sectional shape of the U-shaped portion 16 may be a cross-sectional shape in which the relationship described above is (OP) <(O-Q) <(OR), and even in that case, The impact when the lid 3 reaches the fully open position is mitigated, and the same effect as described above can be obtained.

Further, as described above, even when the eaves portion 33 is formed of a synthetic resin in a plate shape and the wall thickness thereof is relatively thin, the protruding portions 51, 51 have other protruding portions. The wall thickness is thicker than the position. Therefore, due to the design requirement of the lid 3 or the convenience of molding, it is expected that the eaves portion 33 is formed into a plate shape having a relatively thin thickness, and the eaves portion 33 is likely to have a smaller thickness with the passage of use period. The occurrence of the whitening phenomenon on the surface side of the portion contacting the character-shaped portion 16 is prevented in advance. Therefore, even when the eaves portion 33 has a plate shape, it is possible to prevent the deterioration of the appearance quality with the passage of the usage period.

In the above description, the main body side hinge portion 13 is mainly provided with the U-shaped portion 16 which is the main body side regulating portion of the present invention, while the lid side hinge portion 32 is provided with the lid side regulation portion of the present invention. However, the present invention is not limited to this. In addition to the main body side hinge portion 13 and the lid side hinge portion 32, the main body side regulating portion and the lid side regulating portion of the present invention are not limited to this. It may be provided on the lid 3. Even in that case, it is possible to obtain the same effects as those of the above-described embodiment.
